class BOPAlgo_WireSplitter
   - static function:
Standard_Real Angle2D (const TopoDS_Vertex& aV,
                         const TopoDS_Edge& anEdge,
                         const TopoDS_Face& myFace,
                         const GeomAdaptor_Surface& aGAS,
                         const Standard_Boolean bIsIN)
The treatment of circles has been chenged to prevent
the loss of accuracy due to small differences in large values.
